56,60:2'',3''][5,6]fullerene-C60-Ih is widely used as an acceptor material in the active layer of organic solar cells (OSC)[2]
56,60:2'',3''][5,6]fullerene-C60-Ih is also known as ICBA or IC60BA. ICBA is one of the fullerene derivatives used in organic solar cells (OSC). Due to the shallow lowest unoccupied molecular orbital (LUMO) level, it can replace the commonly used PCBM70 to improve the performance of bulk heterojunction solar cells[1].
A ternary bulk heterojunction system (BHJ) may be fabricated with ICBA/ low band gap polymer, for IR sensitized organic solar cells. 1-3ICBA/thiazolo-thiazolo donor polymer blend may be used to enhance the charge generation in BHJ solar cells.
ICBA is a C60 derivative that can be synthesized from C60 and indene. It is an acceptor material with shallow lowest occupied molecular orbital(LUMO) which can be used to enhance the performance of polymeric solar cells(PSCs).
